UNLABELLED BACKGROUND The use of iodinated contrast media in small-animal positron emission tomography (PET)/computed tomography (CT) could improve anatomic referencing and tumor delineation but may introduce inaccuracies in the attenuation correction of the PET images. This study evaluated the diagnostic performance and accuracy of quantitative values in contrast-enhanced small-animal PET/C...
A 51-year-old man on maintenance haemodialysis developed an acute and dramatic swelling of the thyroid and salivary glands, following administration of iodine containing contrast media. He underwent an aortofemoral angioplasty for peripheral vascular disease requiring 300ml of Visipaque 320 contrast media; the following day he developed a grossly enlarged, tender thyroid with swelling and tende...
We determined whether pituitary adenylate cyclase-activating polypeptide 38 (PACAP38) prevents contrast-induced nephropathy using human renal proximal tubule epithelial (HK-2) cells and homozygous endothelial nitric oxide synthase-deficient (eNOS(-/-)) mice as a novel in vivo model. Cultured HK-2 cells were pretreated with 10(-9)-10(-6) mol/L PACAP or vasoactive intestinal peptide (VIP) for 1 h...
Cardiac perfusion studies using computed tomography are a common tool in clinical practice. Recent technical advances and the availability of dedicated small animal scanners allow the transfer of these techniques to the preclinical sector in general and to mouse models of cardiac diseases in particular. This necessitates new requirements for contrast injection techniques as a rapid transport of...
The results of this study has revealed a significant increase in I(131) uptake of cultivated thyroid gland in the media containing petroleum ether extract of Commiphora mukul. Besides, T(3) resin uptake, protein bound iodine as well as free thyroxine index in the media are also observed to be significantly (P 0.001) increased. When explants are cultivated in the media containing melatonin, ther...
X-ray based micro-computed tomography (CT) and micro-digital subtraction angiography (DSA) are important non-invasive imaging modalities for following tumorogenesis in small animals. To exploit these imaging capabilities further, the two modalities were combined into a single system to provide both morphological and functional data from the same tumor in a single imaging session. The system is ...
BACKGROUND Millions of interventional pain procedures are performed each year in the United States. Interventional pain physicians commonly administer radiocontrast media (RCM) under fluoroscopy for these procedures. However, RCM can cause various types of hypersensitivity or allergic type reactions, in an acute or delayed fashion. Furthermore, some patients report a prior history of hypersens...
Transcatheter arterial embolization has become a common management option for intractable postpartum uterine hemorrhage. Iodinated contrast agents are commonly used for embolotherapy but cannot be used in patients with renal dysfunction or iodine allergy. A 37-year-old woman spontaneously delivered a healthy girl but developed severe postpartum uterine hemorrhage, probably due to placenta accre...
